Description

Technical Field

[0001] This utility model relates to the field of detonating cord processing technology, and in particular to a pressure wheel device for industrial detonating cord making. Background Technology

[0002] Detonating cord is a cord-shaped blasting device made of a core wire, core explosive, and several layers of cotton thread and flat wire wrapped together. It is used to directly detonate explosives in contact with it. It is highly sensitive and can easily explode when subjected to friction, impact, bullet penetration, or combustion.

[0003] During production, detonating cord is pressed by a pressure roller and wound up by a take-up roller and a release roller. The pressure roller is usually mounted directly on the processing table. Due to its material properties, the detonating cord is prone to loosening during winding. The fixed installation of the pressure roller makes it difficult to adjust the pressure position, resulting in a loose detonating cord during winding. When the detonating cord is loose, it may disconnect from the pressure roller, making it difficult for the pressure roller to contact the moving detonating cord. This makes it difficult for the hub groove on the pressure roller to properly press the detonating cord, resulting in a loose material in the detonating cord and affecting its quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem of loose detonating cord during the pressing process in the prior art, and to propose a pressing wheel device for industrial detonating cord making.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A pressure roller device for making industrial detonating cord includes a base, a vertical plate, a pay-off roller, a take-up roller, support rods, and a pressure roller. The pressure roller is mounted on the support rods. A guide rod is fixedly mounted on the vertical plate. A rack is slidably sleeved on the guide rod, and two support rods are mounted on the rack. A frame is fixedly mounted on the pressure roller, and a movable rod is slidably sleeved within the frame. A spring is welded between the movable rod and the frame, and a clamping plate for applying pressure to the detonating cord is fixedly mounted on the movable rod.

[0007] Preferably, the upright plate is vertically arranged on both sides of the base, and the two guide rods are vertically arranged correspondingly.

[0008] Preferably, a motor is fixedly installed on the upright plate, and the output end of the motor is fixedly connected to a rotating shaft that is connected to two racks. The rotating shaft is horizontally arranged, and a gear that meshes with the two racks is fixedly installed on the rotating shaft.

[0009] Preferably, the support rod is horizontally arranged, a guide groove is provided on the upright plate, and a guide block extending into the guide groove is fixedly installed on the support rod.

[0010] Preferably, the frame is horizontally positioned on both sides of the pressure roller, the spring is horizontally welded to one side of the moving rod extending into the frame, the clamping plate extends into one side of the pressure roller along with the moving rod, and the clamping plate is an arc-shaped structure adapted to the detonating cord.

[0011] Preferably, a limiting frame connected to a moving rod is slidably sleeved on the frame. The limiting frame has a T-shaped structure and a locking bolt corresponding to the frame is threaded onto the limiting frame.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model uses a motor to drive a rotating shaft to drive a gear to pull two racks. When the racks move, they drive the support rod and the pressure roller to move in opposite directions, thereby adjusting the distance between the two pressure rollers. The left pressure roller can lift and press the lower end of the detonating cord, and the right pressure roller can tighten the moving detonating cord.

[0014] 2. This utility model uses frames on both sides of the pressure rollers to compress the detonating cord. The specifications of the detonating cord compress the clamping plate, and the clamping plate drives the moving rod to slide within the frame. This allows the clamping plate to compress the moving detonating cord from both sides. Through the cooperation of the two pressure rollers and the clamping plate, the detonating cord can be effectively compressed. Attached Figure Description

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-Figure 3A pressure roller device for making industrial detonating cord includes a base 1, a vertical plate 2, a wire feeding roller, a wire taking-up roller, a support rod 3, and a pressure roller 4. The pressure roller 4 is mounted on the support rod 3. Guide rods 8 are fixedly installed on the vertical plate 2. The vertical plate 2 is vertically arranged on both sides of the base 1, and the two guide rods 8 are vertically arranged correspondingly. The wire feeding roller and the wire taking-up roller can realize wire feeding and wire taking-up after being energized. This technical solution is the prior art and will not be described in detail here.

[0021] A rack 9 is slidably sleeved on the guide rod 8, and two support rods 3 are mounted on the rack 9. The support rods 3 are horizontally positioned, and a guide groove 7 is provided on the upright plate 2. A guide block 6 extending into the guide groove 7 is fixedly installed on the support rod 3. The guide rod 8 guides the rack 9, so that the rack 9 can smoothly pull the support rod 3 when it moves. Through the cooperation of the guide block 6 and the guide groove 7, the other end of the support rod 3 can be guided and limited, so that the support rod 3 can smoothly drive the pressure roller 4 to pull when it moves.

[0022] A motor 10 is fixedly installed on the upright plate 2, and the output end of the motor 10 is fixedly connected to a rotating shaft 11 that is connected to two racks 9 for transmission. The rotating shaft 11 is horizontally set, and a gear 12 that meshes with the two racks 9 is fixedly installed on the rotating shaft 11. When the motor 10 is powered on, it drives the rotating shaft 11 to rotate. This technical solution is existing technology and will not be elaborated on here.

[0023] When the detonating cord is relatively loose during unwinding, the output end of the motor 10 drives the rotating shaft 11 to rotate clockwise. When the rotating shaft 11 rotates, it drives the gear 12 to pull the two meshing racks 9. When the two racks 9 move towards each other, they drive the support rod 3 and the pressure roller 4 to move synchronously. The left pressure roller 4 can lift and squeeze the upper end of the detonating cord, and the right pressure roller 4 can apply pressure to the lower end of the detonating cord, so that the detonating cord is relatively tight during unwinding and remains balanced when it is wound onto the take-up roller.

[0024] A frame 13 is fixedly installed on the pressure roller 4, and a moving rod 14 is slidably sleeved inside the frame 13. A spring 15 is welded between the moving rod 14 and the frame 13. A clamping plate 16 for applying pressure to the detonating cord is fixedly installed on the moving rod 14. The frame 13 guides the moving rod 14 so that the moving rod 14 can smoothly pull the clamping plate 16 when it moves.

[0025] The frame 13 is horizontally positioned on both sides of the pressure roller 4. The spring 15 is horizontally welded to one side of the moving rod 14 extending into the frame 13. The clamping plate 16 extends into the pressure roller 4 along with the moving rod 14. The clamping plate 16 is an arc-shaped structure adapted to the detonating cord. A limiting frame 5 connected to the moving rod 14 is slidably sleeved on the frame 13. The limiting frame 5 is a T-shaped structure, and a locking bolt corresponding to the frame 13 is threaded onto the limiting frame 5.

[0026] The specifications of the detonating cord will compress the clamping plate 16, and the distance between the two clamping plates 16 can be adjusted by the limiting frame 5, so that the detonating cord can always be in contact with the pressure roller 4 when it is being released, thereby increasing the degree of contact between the detonating cord and the pressure roller 4 and improving the efficiency of the detonating cord pressing.

[0027] The functional principle of this utility model can be explained through the following operation modes:

[0028] The wire feeding roller feeds the detonating cord, allowing it to pass through two clamping plates 16 in sequence and extend onto the take-up roller.

[0029] The specifications of the detonating cord will abut against the clamping plate 16, causing the clamping plate 16 to drive the moving rod 14 to slide within the frame 13. The spring 15 is under force, and the moving rod 14 drives the limiting frame 5 to slide within the frame 13 when it moves. The operator manually applies pressure to the limiting frame 5, causing the limiting frame 5 to drive the moving rod 14 to move within the frame 13, leaving a small gap between the clamping plate 16 and the detonating cord. The locking bolt is used to connect the limiting frame 5 and the frame 13.

[0030] When the detonating cord is relatively loose during the laying process;

[0031] The output end of the motor 10 drives the rotating shaft 11 to rotate. The rotating shaft 11 drives the gear 12 to pull the two meshing racks 9. When the racks 9 slide towards each other on the guide rod 8, they drive the support rod 3 to move. The support rod 3 drives the guide block 6 to slide in the guide groove 7. When the two support rods 3 move towards each other, they drive the two pressure rollers 4 to press the detonating cord. The pressure rollers 4 are always in contact with the detonating cord through the two corresponding clamping plates 16, so that the detonating cord is always kept taut when pressing the cord.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
